Well, since it’s vaguely on-topic… I recently attended a tech conference and after noting that most of the presenters were men, deliberately attended (with one exception for a session I thought would not be useful to me at all) all the sessions presented by women that I could. I ended up going to at least a couple that I probably wouldn’t have without this consideration and ended up seeing 4 presentations from men and 6 (could have been 7) from women. Including timeslot conflicts 33% of all sessions had at least one woman presenting. I noted on the conference feedback that this was an improvement from last year (25%), and that the diversity was otherwise a little lacking (100% white, and this city isn’t that homogeneous).
